I sorted through the log file and pulled some representative lines that show both myself and others trying to load the post-sitemap page. I am 71.1.237.0, you can see I accessed the sitemap index in the morning and just the posts page failed. I have not included the many times throughout the day where I was testing the post-sitemap, but I did include below where I tried loading the .xsl version. The other examples look to be bots and the validators that were visiting the page.
